The sun is getting brighter, and you can feel the heat and the summer vibes.

It's a pleasure to be outside in the garden and greenhouse with an average temperature of more than 10 degrees and over 200 hours of sunshine.


Greenhouse Maintenance

Regular greenhouse maintenance ensures optimal growth conditions for your plants and prolongs the lifespan of your greenhouse. May is an ideal time to focus on these tasks, setting the stage for a productive growth season.

  • Ensure all installations, such as automatic watering systems, are functioning correctly.
Greenhouse Chores
  • Before permanently placing your plants in the greenhouse, expose them there for a few hours daily to acclimate them to the new conditions.
  • Sow heat-demanding crops at the end of May.
  • Monitor for the Lily Beetle and remove it before laying eggs.
  • For a head start with corn, beans, squash, pre-sprout them in the greenhouse.
  • Regularly water newly planted plants during dry periods.
  • Remove side shoots from tomatoes sown in April for better growth. Consider daily flower shaking for pollination.
  • Air out often, especially as temperatures can reach 30 degrees. Start airing out every day.
  • Anticipate the growth of your plants; ensure you have necessary plant hangers, potholders, plant spirals, wire kits, and eyelets for future sun shielding or support.
Garden Tips
  • Repot fragile flowers and herbs at the end of May.
  • Prune flowering shrubs after blooming to stimulate new growth.
  • Plant colorful summer flowers to liven up the garden.
  • Sow a flower meadow or plant a biodiversity bed with native plants to attract bees, butterflies, and other beneficial insects. Choose plants with different flowering times for prolonged food sources.
  • Remove annual weed plants early while they are still small and easy to handle.
  • Create natural shade areas by planting trees or bushes.
  • Experiment with plant combinations in your beds for visual interest. Combine plants with different heights, colours, and textures.
  • Design small, isolated garden rooms for cozy, intimate areas away from everyday stress.
  • Different garden rooms can attract various wildlife; for instance, a wildflower area attracts bees and butterflies, while a water area attracts birds and insects.
  • Dividing the garden into rooms allows better control of plant placement, accommodating different light and soil conditions for a broader plant selection.
